Pregnancy brings a flood of new medical decisions, and knowing which questions to raise with your gynecologist or OB-GYN can shape the health of both you and your baby. The visits are often short, and it is easy to walk out wishing you had asked about a screening test, a medication sitting in your cabinet, or what your options are for delivery. The questions below are drawn from what the clinical evidence says actually matters at each stage, from the first trimester through postpartum planning.
What Genetic Screening Is Available, and How Accurate Is It?
One of the earliest questions worth bringing up is whether you should have non-invasive prenatal testing, commonly called NIPT. This blood test analyzes fragments of placental DNA circulating in your bloodstream and can flag chromosomal conditions like Down syndrome as early as ten weeks. For the most common conditions it screens for, the test is highly sensitive. One study found that NIPT detected trisomy 21 (Down syndrome) and trisomy 18 with 100% sensitivity, though the positive predictive value for trisomy 21 was about 92% and lower for rarer conditions.1PubMed Central. Amniocentesis and Next Generation Sequencing (NGS)-Based Noninvasive Prenatal DNA Testing (NIPT) for Prenatal Diagnosis of Fetal Chromosomal Disorders A separate analysis of over 300 high-risk NIPT results confirmed chromosomal abnormalities in about 64% of cases overall, with trisomy 21 again showing the highest confirmation rate at roughly 69%.2PubMed Central. Analysis of diagnostic consistency rate and pregnancy outcomes in pregnant women with high-risk NIPT undergoing transabdominal amniocentesis
The practical takeaway: a positive NIPT result is not a diagnosis. Because NIPT reads placental DNA rather than the baby’s DNA directly, there can be mismatches between the two. Confined placental mosaicism, where the placenta carries a chromosomal abnormality that the fetus does not, is one reason false positives occur.3PubMed Central. Inconsistency between non-invasive prenatal testing (NIPT) and conventional prenatal diagnosis due to confined placental and fetal mosaicism: Two case reports Ask your provider what happens if your NIPT comes back positive, whether amniocentesis or chorionic villus sampling would be recommended to confirm the result, and how the timing of those follow-up tests fits into your pregnancy timeline.
Which Medications and Supplements Are Safe?
Many people assume common over-the-counter painkillers are fine during pregnancy, but not all of them are. Nonsteroidal anti-inflammatory drugs like ibuprofen and naproxen carry real risk in the third trimester. A meta-analysis found that NSAID exposure late in pregnancy raised the risk of premature closure of the ductus arteriosus, a critical fetal blood vessel, by roughly fifteen-fold compared to placebo.4PubMed. Nonsteroidal antiinflammatory drugs during third trimester and the risk of premature closure of the ductus arteriosus: a meta-analysis This is not a small or theoretical concern. Ask your gynecologist for a clear list of what you can take for headaches, muscle pain, allergies, and heartburn at each stage of pregnancy. Acetaminophen is generally the go-to, but even that deserves a conversation about dosing.
On the supplement side, folic acid is one of the most established recommendations in prenatal care. The U.S. Public Health Service has recommended that anyone who could become pregnant take 400 micrograms daily to help prevent neural tube defects, which form within the first 28 days after conception, often before you even know you are pregnant.5PubMed Central. Folic Acid and the Prevention of Birth Defects: 30 Years of Opportunity and Controversies If you are already pregnant and were not taking folic acid beforehand, still bring it up. Your provider can advise on the right dose, especially if you have risk factors that call for a higher amount.
Should I Be Screened for Gestational Diabetes?
Gestational diabetes can develop in any pregnancy, and most guidelines recommend screening between 24 and 28 weeks. But the testing process itself can feel confusing because different medical organizations use slightly different approaches. Some follow a one-step test using a 75-gram glucose drink with specific blood sugar thresholds at fasting, one hour, and two hours. Others, including the American College of Obstetricians and Gynecologists, prefer a two-step approach: a 50-gram glucose challenge first, and if that is elevated, a longer three-hour test to confirm.6PubMed Central. Screening and Diagnosis of Gestational Diabetes Mellitus, Where Do We Stand
Ask your provider which method they use and what the timing looks like. In some settings, when a diagnostic glucose tolerance test is needed after an initial screen, it happens about ten days later.7Diabetes Care. Prevalence and Timing of Screening and Diagnostic Testing for Gestational Diabetes Mellitus: A Population-Based Study in Alberta, Canada If you have risk factors such as a family history of diabetes, a high BMI, or a previous pregnancy with gestational diabetes, ask whether earlier screening makes sense for you.
What About Preeclampsia Risk?
Preeclampsia is a condition involving dangerously high blood pressure that can develop in the second half of pregnancy, and it is a leading cause of serious complications for both mother and baby. Many people do not realize there is a simple preventive measure available. Research has shown that starting low-dose aspirin at or before 16 weeks of gestation dramatically reduced the risk of preterm preeclampsia, cutting it by about 89% in a meta-analysis, though it did not significantly affect the risk of preeclampsia occurring at full term.8Fetal Diagnosis and Therapy. Early Administration of Low-Dose Aspirin for the Prevention of Preterm and Term Preeclampsia: A Systematic Review and Meta-Analysis The timing matters enormously here: the benefit came from starting early. Ask your gynecologist at your first prenatal visit whether you are a candidate for low-dose aspirin, especially if you have a history of preeclampsia, chronic hypertension, or other risk factors.
How Does My Age or Health History Affect This Pregnancy?
If you are over 35, or if you have a chronic condition like hypertension, diabetes, or an autoimmune disorder, your pregnancy may be managed differently. Advanced maternal age is associated with higher rates of preexisting conditions, and managing those conditions alongside pregnancy requires a clear plan. The relationship between age and underlying health issues means that monitoring and surveillance often need to increase.9PubMed Central. Clinical Outcomes in High-Risk Pregnancies Due to Advanced Maternal Age Rather than waiting for your provider to label your pregnancy “high-risk,” ask directly: does anything about my health history change the schedule of visits, tests, or ultrasounds? Are there specialists I should see? Getting this conversation on the table early prevents surprises later.
What Vaccinations Should I Get During Pregnancy?
Prenatal vaccines protect both you and your newborn, but the timing window can be narrow. The flu shot and Tdap (which protects against whooping cough) are standard recommendations, and newer vaccines like the RSV vaccine have specific timing considerations. Research on maternal RSV vaccination shows that getting vaccinated at least five weeks before delivery results in the highest transfer of protective antibodies to the baby through the placenta. Vaccination closer to delivery, only two to four weeks before birth, led to significantly lower antibody transfer.10PubMed Central. Enhanced placental antibody transfer efficiency with longer interval between maternal respiratory syncytial virus vaccination and birth This means the conversation about vaccines should not wait until the third trimester is almost over. Ask early enough to plan the ideal timing, and ask again if your due date shifts.
Can I Exercise, and Are There Limits?
For most healthy pregnancies, exercise is not only safe but beneficial. Guidelines from countries around the world agree on a core list of conditions where exercise is not recommended, including persistent vaginal bleeding, preeclampsia, premature labor, and incompetent cervix. They also agree on a set of relative cautions such as anemia, multiple gestation, and thyroid disease, where you and your provider need to weigh the benefits against the risks together.11PubMed Central. Guidelines for Physical Activity during Pregnancy: Comparisons From Around the World If you were active before pregnancy, ask what you can continue and what needs modification. If you were not exercising regularly, ask what is safe to start. The answer will depend on your specific pregnancy, and a blanket “take it easy” from well-meaning friends is not a substitute for clinical guidance.
When and How Will I Be Tested for Group B Strep?
Group B streptococcus, or GBS, is a common bacterium that many adults carry without symptoms. But during delivery it can pass to the baby and cause serious infection. The standard recommendation is to screen with a vaginal swab at 35 to 37 weeks of gestation.12Gynecologic and Obstetric Investigation. Timing of Group B Streptococcus Screening in Pregnancy: A Systematic Review If you test positive, you will receive antibiotics during labor to reduce the risk of transmission. The screening window is important because colonization status can change; a test done too early may not reflect your status at delivery. A systematic review found that even with optimal timing, about 6% of carriers are missed by antenatal cultures.12Gynecologic and Obstetric Investigation. Timing of Group B Streptococcus Screening in Pregnancy: A Systematic Review Screening at 36 weeks appears to improve detection of colonized women compared to earlier timing.13PubMed Central. Antenatal screening for Group B Streptococcus: a diagnostic cohort study
Ask your provider when they plan to test you and what will happen if you go into labor before the test is done or if your results are positive. If you have a penicillin allergy, mention it early: guidelines include specific alternative antibiotic regimens for allergic patients.14Obstetrics & Gynecology. Perinatal Infections Due to Group B Streptococci
Should I Be Screened for Depression or Anxiety?
Mental health during pregnancy gets far less attention than it deserves. Rates of depression and anxiety during pregnancy are surprisingly high; in one study, about a third of pregnant participants were diagnosed with major depression, an anxiety disorder, or both.15PLoS ONE. Comparison of mental health screening tools for detecting antenatal depression and anxiety disorders in South African women Validated screening questionnaires exist and perform well. The Edinburgh Postnatal Depression Scale, despite its name, is effective during pregnancy too: a meta-analysis found that at a commonly used cutoff, it correctly identified depression with sensitivity and specificity both around 84 to 87%.16PubMed Central. Identification of depression and anxiety during pregnancy: A systematic review and meta-analysis of test accuracy The PHQ-9, a widely used questionnaire in primary care, similarly showed strong accuracy for identifying prenatal depression.17PubMed. Validation of the Patient Health Questionnaire (PHQ)-9 for prenatal depression screening
You should not have to wait until after delivery to address how you are feeling. Ask whether your practice routinely screens for perinatal mood disorders, and at what visits. If you have a history of depression or anxiety, bring it up at your first appointment so that monitoring and support can be built into your care plan from the start.
What Should My Birth Plan Include, and How Flexible Should It Be?
Writing a birth plan is worth doing, but its greatest value may not be the plan itself. Research suggests that birth plans work best as tools for shared decision-making: they open a conversation between you and your care team and help you feel a sense of control over the process. Critically, discussing different scenarios ahead of time, including ones that deviate from your preferences, can help you feel more prepared if things do not go as hoped.18PubMed. The role of birth plans for shared decision-making around birth choices of pregnant women in maternity care: A scoping review
If you are curious about elective induction at 39 weeks, ask about the evidence. A study comparing elective induction with spontaneous labor in first-time mothers at 39 or more weeks found similar cesarean delivery rates (about 12% vs. 18%, with no statistically significant difference) and similar neonatal outcomes between the two groups.19PubMed Central. Benefits and risks of induction of labor at 39 or more weeks in uncomplicated nulliparous women: a retrospective, observational study Ask your provider how they approach induction, under what circumstances they would recommend it, and how your specific health profile factors in. A birth plan that accounts for contingencies is more useful than one built around a single ideal scenario.
Is It Safe to Travel While Pregnant?
Travel comes up frequently, especially in the second trimester when many people feel their best. Air travel is generally considered safe for uncomplicated pregnancies, but it is not risk-free. Cabin altitude reduces your blood oxygen saturation by about 10%, which stays within safe limits for most healthy pregnancies.20Obstetrics, Gynaecology & Reproductive Medicine. International travel during pregnancy: a review of current literature and guidelines However, a review commissioned by the European Board and College of Obstetrics and Gynaecology found significantly increased risks of deep venous thrombosis, airborne infection, and preterm labor associated with flying, especially for those with pre-existing medical conditions.21PubMed. Commercial Air And High-Altitude Travel by Pregnant Women: A scientific review commissioned by the European Board and College of Obstetrics and Gynaecology (EBCOG)
If you have a trip planned, ask about compression stockings for blood clot prevention, whether you need a medical clearance letter (most airlines require one after 36 weeks), and how to wear a seatbelt properly: chest strap between the breasts, lap strap across the top of the thighs, under the belly, not over it.20Obstetrics, Gynaecology & Reproductive Medicine. International travel during pregnancy: a review of current literature and guidelines If you have complications or a high-risk pregnancy, the calculus changes and a frank conversation with your provider is essential before booking anything.
Does My Job or Environment Pose Any Risk?
Occupational exposures are easy to overlook, but they deserve a direct question. A study comparing pregnancy outcomes across different workplace exposure types found that women exposed to physical workplace hazards had newborns with measurably lower arterial oxygen levels compared to controls, though the values were still within average range overall.22PubMed Central. Occupational Exposure during Pregnancy and Effects on Newborns: A Nested Case-Control Study Chemical and biological workplace exposures are also tracked as potential concerns. If your work involves chemicals, radiation, heavy lifting, prolonged standing, or shift work, tell your gynecologist specifically what you are exposed to. They can help you assess whether workplace accommodations or modifications are warranted and provide documentation if your employer requires it.
What Happens After the Baby Is Born?
Postpartum care is part of your pregnancy conversation too, and it is worth raising before delivery. The American College of Obstetricians and Gynecologists recommends that all women have contact with a maternal care provider within the first three weeks after birth, with ongoing care as needed and a comprehensive postpartum visit no later than 12 weeks after delivery.23Obstetrics & Gynecology. Consensus Bundle on Postpartum Care Basics: From Birth to the Comprehensive Postpartum Visit In practice, many people fall through the cracks between delivery and that visit. Ask before your due date what postpartum follow-up looks like at your practice, how to reach someone if you have concerns about bleeding, infection, or mood changes in those first weeks, and whether telehealth visits are available.
Have I Chosen a Pediatric Provider?
This question seems like it belongs to the baby rather than to you, but your gynecologist’s office is a good place to start the conversation. Having a designated pediatric provider lined up before birth matters for practical reasons: newborn screening results, which check for rare but serious metabolic and genetic conditions, need to reach a specific provider who can follow up promptly. Research has found that when infants lack a designated pediatric provider, communication delays and procedural errors can hinder the identification of critical conditions or the follow-up of incomplete screening samples.24PubMed Central. Providers’ Perspectives Related to Parents’ Choice of Pediatric Provider of Record and Newborn Screening: A Qualitative Study Ask your OB-GYN’s office for recommendations, whether your insurance plan affects your choices, and what timeline you should aim for. Having a pediatrician selected by the middle of the third trimester gives you one less thing to worry about at delivery.
